Photovoltaic Cell Test-Perovskite & Organic Photovoltaic

It is a mineral name, which was discovered by Rose in the Ural Mountains in 1839 and named after the Russian geologist Perovski. Perovskite materials often have low carrier recombination probability and high carrier mobility, and are ideal materials for solar cells.

「Structure of Perovskite Battery」

Most advanced perovskite solar cell structures are based on five components: transparent conductive oxide, electron transfer layer (ETL), perovskite, hole transfer layer (HTL), and metal electrode. Understanding and optimizing the energy levels and interactions of different materials on these interfaces is a very exciting research field, which is still under discussion.

「Film Forming Method of Perovskite」

The key to improve the photoelectric conversion efficiency of perovskite solar cells is to optimize the film morphology. The film-forming method often used in the laboratory is one-step or two-step process deposition. For the application demand of perovskite thin film with large area and low cost, process equipment such as slit coating, printing, and spraying are also used to make perovskite solar cells.

「The Future of Perovskite」

Future research on perovskite may focus on reducing recombination through passivation and defect reduction strategies and improving efficiency by including two-dimensional perovskite and more optimized interface materials. The charge extraction layer may be transferred from organic materials to inorganic materials to improve efficiency and stability. Improving stability and reducing the impact of lead on the environment remain important areas.
